Question

With the help of an example, explain how will you calculate the speed from a distance time graph​

Answer 1

Answer:

If the speed of an object changes, it will be accelerating or decelerating . This can be shown as a curved line on a distance-time graph. If an object is accelerating or decelerating, its speed can be calculated at any particular time by: drawing a tangent to the curve at that time.

Explanation:

Hope you satisfy for this answer and Mark as a the brainlist answer

Answer 2

Explanation:

• if an object moves along a straight line ,the distance travelled can be represented by a distance time graph

• calculate the speed of the object represented by the green line in the from 0 to 4s

• change in distance (8-0)=8m

• change in time (4-0)=4s
